The factors that caused the war of Indochina were: the end of the Second World War, which brought as a consequence the surrender of Japan and the withdrawal of its troops from the territory and the emergence of a communist guerrilla that declared the Democratic Republic of Vietnam. The president of France, de Gaulle, sent troops to reestablish control over the territory. The proposal was for Vietnam to become independent and become part of the French Union. This was not accepted and the war intensified. With the rise of Communist China, the Indochinese war enters the framework of the cold war. China grants its military support to the guerrillas in Vietnam and the French army is defeated in 1954. The Geneva agreements were signed where they declared themselves independent Cambodia and Laos, and Vietnam was divided into two territories with the purpose of having Free elections the following year to be able to reunify the country.
